Mechanism of photoacoustic imaging
WebBy contrast, photoacoustic imaging is a non-invasive and non-radiative imaging modality that is sensitive to blood, by using hemoglobin as the … WebSep 5, 2024 · Photoacoustic (PA) imaging uses optical absorption as the contrast mechanism and can thus visualize the optical properties of tissue [ 1 ]. One of the most widely imaged endogenous chromophores is hemoglobin in the red blood cells, which provides high contrast and high resolution PA images of vasculature in vivo [ 2, 3, 4 ].
